BACKGROUND
Data from studies of angiotensin-converting enzyme inhibitors provide evidence that the renin-angiotensin-aldosterone system plays a role as a mediator of atrial remodeling in atrial… (More)

Recently, several cases of skin injuries have been detected in patients undergoing cardiac radiofrequency catheter ablation. These procedures were performed on a biplane X-ray system used in a large… (More)

OBJECTIVES
This study was designed to evaluate the efficacy of atenolol for the long-term management of patients with vasovagal syncope. The primary hypothesis was that atenolol is not superior to… (More)

In order to elucidate the electrophysiological nature of the short P-R interval we have studied 15 patients with this phenomenon and a normal QRS complex in the electrocardiogram; none of them had a… (More)

UNLABELLED
INTRODUCTION AND PURPOSES: Autonomic nervous system plays an important role in the pathogenesis of vasovagal/vasodepressor syncope and may also be assessed by the RR variability analysis.… (More)

In this prospective, controlled and randomized cross-over study we tried to establish the efficiency and safety of flecainide vs procainamide for the treatment of acute atrial fibrillation. Eighty… (More)

INTRODUCTION AND OBJECTIVES
An important limitation of the ablation with standard catheter is the volume and limited depth of the lesions created. The irrigated catheters, due to a larger and deeper… (More)
